The 2005/2006 senior design group has already been working on creating a single robot finger with three independent joints. The 2006/2007 project has been split into two design projects. This project will be developing a control feedback system while the other project will be working on the extension and/or improvement of the mechanical design.
The 2005/2006 SMA senior design group has already created a single robot finger with three independent joints. The 2006/2007 SMA project has been split into two design teams. This team will be developing a control feedback system while the other team will be working on the extension and/or improvement of the mechanical design.
To increase the efficiency of the shape memory alloys (SMA) muscle array, fluid recycling with heating and cooling and displacement sensing systems are to be designed and built. The fluid recycling system will allow the SMA muscle array to operate without requiring external fluid sources. The displacement sensing system will allow the SMA muscle array to shut off fluid flow at desired displacements.

The main focus of this project is to develop bio-inspired feedback system for a robotic hand. Many bio-inspired robotic hands have already been created. However, there has not been a large amount of sensory feedback included within these systems. The goal of this project is to implement temperature and pressure sensory feedback to the bio-inspired robotic hand to allow the muscle array to have more accurate control of the system.

The fluid recycling system will allow the SMA muscle array to operate without requiring external fluid sources. The displacement sensing system will allow the SMA muscle array to shut off fluid flow at desired displacements.
The fluid recycling system will consist of an on/off feedback system. This system will be using feedback from temperature sensors to know whether the exiting fluid from the SMA muscle array is the hot or cold fluid to direct it to the correct reservoir. Once in the correct reservoirs the fluids will be heated and cooled via heat pump.
The displacement sensing system will also consist of an on/off feedback system. The system will measure the displacement of the SMA muscle fibers with a system to be designed and built then shut off the fluid flow once a desired displacement is reached.
The 2005/2006 senior design group has already been working on creating a single robot finger with three independent joints. The 2006/2007 project has been split into two design projects. This project will be developing a sensory feed back system while the other project will be working on the extension and/or improvement of the mechanical design.
In order to create a truly bio-inspired robot hand, the hand must have bio-inspired sensing systems. The main focus will be on pressure and temperature sensing. Additional possibilities that are currently in use with other feedback systems are optical sensors and motion sensors.
Pressure. For pressure sensing, the use of Quantum Tunneling Composites (QTC) are being explored. QTC functions like an insulator (high resistance) when no deformation occurs. With deformation the QTC acts like a conductor and decreases resistance in an exponential manner. This exponential decrease in resistance allows for a large range of forces to be detected. QTC are manufactured in small/thin segments which makes them the perfect choice for an external pressure sensor.
Temperature. To detect temperature, thermocouples will be used. Thermocouples are the most simple and easy to use temperature sensor. No external power supply is necessary for the use of thermocouples and they are relatively inexpensive.
The final goal of the system will be to expand on the evolution of the sensory systems used to control robotic hands. This will help the industry move closer to replicating the human hand in robotic form.
